SPECIFICATION forming part of Letters Patent No. 589,587, dated September 7", 1897.

Application filed November 16, 139,5.'V Serial No. 569,188. {No model.)

.I r., a citizen of the United States, residing at Boston,.in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Copllfinding Machines, of which the following is a specification.

My invention relates to cop-winding 1naehines, and more especially to machines which are adapted for winding cops of the `general character shown and claimed in my United States Letters Patent Nos. 480,158 and 486,745.

The object of the invention is to provide a simple,cheap, and effective machine for winding cops, which shallbe light of structure and capable of operating at a high speed andiat the saine time be capable of accomplishing the winding of the cops in a satisfactory inanner; and to these ends my invention consists in the various features of construction and arrangement of parts for accomplishing the various purposes, substantially as hcrei nafter more particularly set fort-h.

Referring to the accompanying' drawings, wherein I have illustrated a preferred e m bodirnentof my present invention, Figure l is a front `elevation of a cop-winding machine. Fig. i. is a horizontal section of Fig. l on the plane of the arrows. Fig. 3 is an end elevation, in' part section, of the machine. Fig. et is an enlarged sectional detail showing a means for supporting the outer ends of the cops, and Fig. 5 is an enlarged detail drawing showing part of the stop mechanism.

The support for all of the parts consists of a simple liatoblong frame A, adapted to be bolted to a standard and having bosses at the points where the shafts pass through the same. The main driving-shaft G, at the top of the frame, has a fast pulley 7, a loose pul ley S, and a pulley 9 with a V-shaped groove to receive a V-shaped belt l0, the ends of the shaft 6 being constructed to receive the ends of tubes or blocks as, upon which the thread is wound to constitute the bobbins X.

The thread is laid upon each tube by means of a reciprocatingr guide B, the two guides being carried by a rod 12, which slides back and forth in bearings in the frame under the ae- 'tion of a cam C upon a shaft 13, which is provided with a gear 14, driven from a pinion l5 upon a shaft 1G, the latter carrying an expansion-pulley E, around which passes the belt IO.

It has been found desirable in this class of winding-machines to red nce the weight of the parts connected to the reciprocating guides, because if the parts are heavy the momentum is very great when the guides are driven at a .high rate of speed, and there is a tendency to misplace the thread, which, to eiect the wind of my aforesaid Letters Patent, must he laid with the greatest regularity. My effort, therefore, has been to reduce the weight' of these parts, while maintaining the guide in constant Contact with the cop, permitting' them to swing back as the cop increases in size and reciprocating them with the desired speed. I reduce the weight of the cani, forming it so as to constitute practically an open flanged ring 20, mounted hy spokes 2l, eX- tending from a huh 22, angularly upon the shaft 13. This secures all the effective portions ot the cam, dispensing with superiluous weight. I prefer to split the hub 22 at one side and pass a clamping-screw 23 through the slit portion, so as to tightly secure the i cam to the shaft- 13 without the use of any key and the necessity of slotting the shaft.

In order to maintain the belt lO taut,l mount the shaft 13 ina frame F, pivoted to the shaft 16, so as to swing freely, thereby bringing the weight of the frame, shaft 1G, and pulley E to bear upon the belt l0 to keep it under constant tension, and as the frame F swings upon an axis concentric with the axis of the gear le the pinion l5 is maintained in proper relation to the gear l-l regardless of the position of the frame F.

In order to aid in maintaining the belt l0 tight and to prevent any rebound of the frame F, I find it advantageous to use in some cases a weight IV, hung by a cord IV to the frame F, and the cord maybe. passed around a pin IVE on the frame A to steady the frame F and prevent too rapid action.

Each guide B consists of a divided arm 25, extending from a split huh 26, which carries the two cross-pieces 27 28, a dat plate 29, having a V-shaped notch s, and a bent rod 30, hav- IOO ing a guide-eye 31 at the end, screws or bolts passing through the plate 29 and rod SO into the arm and securin g the plate and rod detachably to the arm, thereby permitting the character of the notch and the position of the guide-eye to be altered for different characters of thread.

To the rod 12, between the branches of each split arm 25,is secured a split ring 35, which may be clamped tightly to the rod bya screw 3G, passing through ears 37 of said ring. A spring 38, connected at one end with a crossbar 27, is attached at the other end to a stud 39 on the ring 35 and tends to carry the upper end of the guide toward the cop while permitting it to swing back readily, the crosspiece 28 by its contact with the long ear 37 limiting the swinging movement of the guide toward the cop. This construction of the guide secures all of the necessary features and actions, while greatly reducing the weight of the parts heretofore employed to secure both the reciprocating and swinging actions.

The rod 12 is driven from the cam C through the medium of a cross-arm 40; clamped tothe rod and forked at one end to embrace a spool 4l, sliding on a rod 42, and the cross-arm carries a pin with an antifriction-roller 43,which extends into the slot of the cam.

To facilitate the support and insertion and removal of the tubular holders or bobbins, I attach to the rod 42 blocks 46, each carrying a swinging arm 47, having a freely-rotatable stud 4S for receiving one end of the bobbin X, which stud is held in place by means of a screw working in the arm and entering a circumferential groove in the stud. The opposite end of the bobbin is supported upon the end of the shaft G, and a spring 49 throws the arm 47 inward, so asto cause its stud to bear firmly against the end of the bobbin. The block 46 is provided with an arm 50, into which screws a set-screw 51, so as to regulate the extent of the inward movement of the swinging arm 47.

In devices of this character it is desirable to automatically throw the apparatus out of operation as soon as a bobbin reaches the proper size. For this purpose I make use of a belt-shifter G', consisting of a yoke 55 upon a sliding shaft 5G, through which yoke passes the driving-belt II. A spring 57 tends to throw the shaft and yoke to a position to shift the belt onto the loose pulley and stop the machine. The frame of the machine is provided with a shoulder u, which is adapted to to be engaged by a projection i; on the beltshifter G, and the spring 57 is so applied as to tend to throw the yoke inward because of the shoulders being bent. At each end of the rod 56 is adjustably mounted an arm 59, through the outer end of which passes ascrew (30,having a milled head 6l at the outer end and a bearing 62 at the inner end. (See Fig. 3.) XVhcn the machine is in operation, the parts are as shown in Fig. 1, with the belt H on the drivin gpulley 7. The parts are so adjusted that when acop reaches'its proper size it bears against the bearing 62, and rocks the arm 59 and sha-ft 5G, carrying the pin fv away from the shoulder u,when the spring` 57 throws the yoke so as to carry the belt I-I onto the idler-pulley S.

The expansion-pulley E is simplified by forming the fixed section (,which is bolted to the shaft 1G, with a long hub 61, threaded at the outer end. The sliding section has a disk G2 and a hollow collar G3, which slides on the hub 61, and an intervening spring G4 tends to throw the section 6 2 outward. A nut 65 turns on the threaded end of the hub, and by turning this nut in one direction the movable section is brought toward the fixed section, and by turning the nut in the opposite direct-ion the movable section is carried outward by the spring. Any suitable means may be employed for locking the nut, but i prefer to make a transverse slit u; in the periphery of the nut at one side, to place a loose perforated disk GS in this slit, and to pass a screw G9 through the slit portion of the nut and through the disk. Then the screw o9 is loosened, the disk will accommodate itself to the movements of the nut, but when the screw is tightened the disk is heldin engagement with the threads of the hub in such manner as to prevent the nut from being turned.
